### Synapse 1.147.0rc1 (2026-02-03)

#### Bugfixes

- Fix memory leak caused by not cleaning up stopped looping calls. Introduced in v1.140.0. ([#&#8203;19416](element-hq/synapse#19416))
- Fix a typo that incorrectly made `setuptools_rust` a runtime dependency. ([#&#8203;19417](element-hq/synapse#19417))

#### Internal Changes

- Prune stale entries from `sliding_sync_connection_required_state` table. ([#&#8203;19306](element-hq/synapse#19306))
- Update "Event Send Time Quantiles" graph to only use dots for the event persistence rate (Grafana dashboard). ([#&#8203;19399](element-hq/synapse#19399))
- Update and align Grafana dashboard to use regex matching for `job` selectors (`job=~"$job"`) so the "all" value works correctly across all panels. ([#&#8203;19400](element-hq/synapse#19400))
- Don't retry joining partial state rooms all at once on startup. ([#&#8203;19402](element-hq/synapse#19402))
- Disallow requests to the health endpoint from containing trailing path characters. ([#&#8203;19405](element-hq/synapse#19405))
- Add notes that new experimental features should have associated tracking issues. ([#&#8203;19410](element-hq/synapse#19410))
- Bump `pyo3` from 0.26.0 to 0.27.2 and `pythonize` from 0.26.0 to 0.27.0. Contributed by [@&#8203;razvp](https://github.com/razvp) @&#8203; ERCOM. ([#&#8203;19412](element-hq/synapse#19412))
